4. Where is the ribosome located in the cell? What is the essential role of the ribosome
in gene expression?
5. In which crucial step of gene expression does the ribosome play a major role:
transcription or translation?
6. How does the ribosome differ in eukaryotes and prokaryotes?
7. Why is transfer RNA, or tRNA, necessary for protein synthesis?
8. What is the role of ribosomal RNA in the ribosome?
9. What happens if there are no ribosomes present in the cell, or if the ribosomes do
not function properly?

4. Ribosomes are tiny glanular structures that are either floating freely in cytoplasm or are bound to endoplasmic reticulum.

5. Translation.

6. Eukaryotic ribosomes are ten times larger than prokaryotic ones.

7. Not sure about this.But they are necessary for protein synthesis as they assemble amino acids into protein chains.

8. Ribosomal RNA is part of ribosome.These complex structures catalyze the assembly of amino acids into protein chains.They also bind tRNAs and various accessory molecules necessary for proteins.

9. When a ribosome is not working,it disassembles into two smaller units.

Explanation:

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
